SEPARATOR.

Specification of Letters Patent.

Patented Jan. 11, 1916.

Application filed January 21, 1915. Serial No. 3,529.

To all whom it may concern.

Be it known that I, JAMEsD. Moonn, a citizen of the United States,residing at North VVilkesboro, in the county of Wilkes and State of North' Carolina, have invented a new and useful Separator, of which thefollowing is a specification.

This invention relates to separators, one of its objects being toprovide a structure of this type particularly designed for use in theseparation of grits from bran and meal, novel means being providedwhereby the separation is effected accurately and readily, the machinebeing of a simple and compact construction.

l/Vith the foregoing and other objects in View which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made within thescope of what is claimed, without departing from the spirit of theinvention.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings :Figure 1 is a vertical longitudinal section throughthe separator. Fig. 2 is a plan view thereof. Fig. 3 is a section online AB Fig. 1. Fig. 4 is an end elevation.

Referring to the figures by characters of reference 1 designates a mainsupporting frame having hangers 2 suspended therefrom and connected tothe side walls 3 of the separator. These side walls are arranged betweenthe sides of the frame 1 and can be connected in any suitable manner,there being a screen 41 extending longitudinally of the separatorstructure for a portion of the length thereof and merging into anotheror coarser screen 5 likewise extended longitudinally. The meeting endsof the two screens 4: and 5 may be mounted on a cross strip 6.

Suitably mounted under the fine screen 4 is a hopper 7 for the receptionof meal passing through said screen, this hopper being adapted todischarge its contents into any suitable receptacle provided therefor.

Extending under the screen 5 is an inclined board 8 adapted to dischargescreenings into a flue 9 which is inclined downwardly and inwardly underthe board 8, there being an outlet spout 10 in the bottom of said flue 9at its lowest point and through which grits are adapted to bedischarged. An outlet spout 11 is provided at the outer end of the flue9 and the top of this outlet spout is curved upwardly and inwardly, asat 12 and terminates adjacent the discharge end of the screen 5, therebeing a passage 18 between the said screen and the top 12 for thereception of tailings. An arcuate wind shield 1 1 extends across theupper end of the flue 9, the upper end of this shield being extendedinto the space between the screen 5 and the inclined board 8, while thelower end of the shield is extended into the spout 11. A blower casing15 is arranged under the hopper 7 and has an outlet flue 16 whichdischarges into the flue 9 close to the outlet 10. It will be seen byreferring to Fig. 1 that the flue 9 has its top bowed upwardly above theoutlet 10, as shown at 17 thus to provide a deflector for air enteringthe flue 9 from flue 16. A pitman 18 is connected to the frame 3 of theseparator and receives motion from a disk 19 secured to a shaft 20 whichis adapted to be actuated in any suitable manner. Thus it will be seenthat rotation of the disk 19 will result in the reciprocation of theseparator screen 4-5.

In using the apparatus the parts are set in motion, after which thematerials to be separated are placed on the screen 4. The finest gradeof material such as meal. will gravitate through the screen 4t and intothe hopper 7, while the coarser material will pass onto the screen 5where a second separation will be effected, the grits passing throughthe screen and onto the inclined board 8 while the coarser material,such as bran, will be discharged as tailings from screen 5 and onto theshield 14 and be directed into the spout 11. The grits discharged ontothe board 8 will gravitate into the upper end of the flue 9 and willdrop across the upper portion of the flue onto the screen 21 which willoperate to spread the grits so that said grits and any particles of branwhich may be adhering thereto will be separated and will then falldownwardly through the screens 21 and onto the bottom of flue 9. As theair enters the lower end of flue 9 from flue 16 it will strike thecurved top wall 17 and thus be deflected downwardly so as to thoroughlyagitate the grits before they pass outwardly through the outlet 10, thisagitation being sufiicient to separate from the grits any bran which maybe adhering thereto so that said bran will thus be blown outwardlyagainst the wind shield 14: and be deflected downwardly into spout 11where it will commingle with the bran discharged into said spout fromthe end of screen 5.

Especial importance is attached to the particular arrangement of thecurved top 17 so that the air current is deflected downwardly onto thebottom of the flue 9 at a point above the outlet 10. The screen 21 is ofthe same mesh as screen 5 and, therefore, as before stated, the grits,when discharged from the board 8 will fall onto this screen 21 and willbe scattered transversely within the flue 9 before falling through thescreen 21, thus insuring the separation from the grits of any branadhering thereto so that the light bran will be blown from the flue 9while the grits will gravitate as before described.

What is claimed is 1. A separator including alining fine and coarsescreens, means for receiving screenings from the fine screen, an outletspout, means for directing tailings into the outlet spout from thecoarse screen, a flue extending downwardly away from the spout, aninclined board for directing screenings from the coarse screen into theflue, a blower casing, and means for directing an air blast from theblower casing and longitudinally of said flue, said flue having anoutlet between its ends, the top of the flue being curved upwardly inthe line of the air cur rent thereby to deflect the current downingsinto the flue, means for directing an air blast longitudinally throughthe flue and against the wind shield into the spout, said flue havingits top bulged upwardlyadjacent the outlet thereby to deflect the aircurrent downwardly against the bottom of the A flue at a-point above theflue outlet. 3. A separator including a screen, an inclined boardthereunder, an outlet spout,

means for directing tailings from the screen and into the spout, a flueextending down-- wardly from the spout, and a screen of the same mesh asthe first named screen for receiving material from the inclined board,said screen being located inthe upper end portion of the flue, and meansfor directing an air current longitudinally within the flu and into theoutlet spout.

In testimony that I claim the foregoing as my own, I have hereto aflixedmy signature in the presence of two witnesses. V
